ad apicem attenuatis nunc valde papilloso-muricatis ; ab E. harhigero 

 differt calyce sa^pius dimidio minore baud villoso ; nuculis ssepius 4 

 fertilibus. — Southern part of California (from Los Angeles, Nevin, 

 &c.) to adjacent Arizona. Not uncommon in collections, bas been 

 confounded at times vvitb botb of the two species mentioned: if it 

 should pass into E. muriculatum, the character of that species would 

 require much extension. It bas been collected by Parry, Lcminuji, 

 Parish, Cleveland, &c.

 persistent.* 



taken for Lehraann's E. diffusum, because of his description of the corolla 

 (" Corolla alba ? magna, tubus calyce paullo longior sensim ampliatus ") ; and 

 Californian specimens of the real E. diffusum were mixed witli it. The origi- 

 nal specimens of the latter do not have the exserted tube of the corolla which 

 marks the present species when in blossom, as does the fruit at maturity. It 

 is the E. nervosum of Kellogg ; but neitlier the leaves nor the sepals are per- 

 ceptibly nervose (the former not "3-5-nerved" nor the latter "3-nerved"), 

 so that the name would be a false one. 



*^* E. Mexicamim, Hemsl. {CipiorjJossum Mexicamim, Schlecht, in Linnaea, 

 & DC. Prodr. x. 156), is an apparently biennial species with slender prickles 

 covering the whole surface of the fruit, but with corolla-tube not exceeding 

 the calyx. 



* ERiTRicniuM, § Plagiobothrys. 

 Good specimens and careful notes, kindly communicated by the Rev. J. C. 

 Nevin of Los Angeles, and a consequent re-examination, enable me to distin- 

 guish the species of the first subdivision in the Syn. Fl. N. Amer. (p. 102) 

 more clearly than is done in tliat work. It will be seen that one of them 

 requires a change of name. 



E. FULVUM, A. DC, the M ijosilis fuh-a , Hook. & Am. Bot. Beechey, p. 38, and 

 I suppose Phifjiohothrys rufescens, Fischer & Mej'er, as appears from tlic habitat, 

 were all founded on the Chilian plant. My specimens of this, from Bertero's
